Is there any way to downgrade Z3+ to Kitkat 4.4.4. ? Cannot find much resources on this! Thanks!

No z3+came with lollipop

Too bad then...that also means all newer phones cannot be downgraded to older versions of Android....seems like Apple way?

Not really like Apple. I mean, if a phone never had any of the previous firmware to begin with, then you won't be able to downgrade it at all. In Apple's case, even the older models get the new IOS versions now and then, so they can be downgraded via jailbreak.

I need 4.44 rom.

[Q] Not up to date with S5 at all. Update to Lollipop and keep root?

My girlfriend has an AT&T Galaxy S5. She's on Android version 4.4.2 (baseband version G900AUCU2AND3, build number KOT49H.G900AUCU2AND3). She's rooted with towelroot.
She's very keen on updating to Lollipop. The reason for this is that she's a very avid photographer and takes many shots on her phone. She is REALLY interested in trying out the RAW image processing.
I'd just like to know if she can update and keep root. So if anyone could help me out here or point me in the right direction since I don't know my way around this forum, that would be fantastic. Thank you very much.
Once we get a leak or the actual release, we won't know what Lollipop will have in store for the Dev's root wise. Everything now is speculative though the International version(G900F) has had good success with root and Lollipop.

I'm sorry, I just saw something after a quick Google that led to believe there *was* a release. So you're saying as of now, there's no Lollipop on G900, root or not?

The g900f, which is the over seas version, has had a limited release with lollipop. AT&T version, G900A, does not have lollipop yet.

No AT&T release as of yet, and even when (IF) it does drop and IF root is obtainable it is a longshot whether or not we will have SafeStrap or any other type of custom recovery

Looking to downgrade from Lollipop 5.0

Hello. I'm not sure if this in the right section if it isn't I'm sorry. Anyways I just recently updated my AT&T Galaxy s5 g900a to lollipop 5.0 and it sucks pretty bad, the color scheme is terrible for my eyes and its just not something I want to get used to. Is there anyway to downgrade back to kitkat on the g900a? If so can you please help, thank you.

If you updated via OTA, unfortunately no, there is no way to downgrade. If you upgraded via a method here on XDA, you should be able to ODIN back to KK. Good luck.

Thanks, I heard that using the s5 with AT&T has a locked bootloader is that a problem or are there ways around that?

Yes it's locked. That's why such a pain to do things. There are workarounds, like safestrap and flashfire, but both of those are limited in what you can flash because of the locked bootloader. You'll have to look around and see what you're most comfortable with. But like I said, if you're using the latest Android version via OTA, there is no workaround that will work. Thanks AT&T

How do I update PingPong Rooted S6 Edge?

Model Number: SM-G925V
Android Version: 5.02
I know I can't use the OTA update, so how do I update?
This totally depends on what your build number is.
If your ROM version is G925VVRU1AOC3 then follow this thread. http://forum.xda-developers.com/ver...nt/trailblazer101-lightlycleaned-rom-t3128758
If your ROM version is G925VVRU1AOE2 and you desire the latest build (which breaks root), I recomend you manually update after you follow this thread. http://forum.xda-developers.com/galaxy-s6-edge/general/sm-g925f-s6-firmware-thread-t3078841
Let me know if you had any issues
Newest update

Does any one know a way to root with current update in place? To be honest I don't much care about the Knox trip. I want to install new roms and I never want to see samsung music player

As far as I am aware, there is no way to root the latest build, and likely never will be. If you read many of the threads, they all say the same thing, namely the OF1 build breaks root, has a kernel date that patches the exploit used in PingPong root, and makes it impossible to downgrade the firmware. There are plenty of ways to trip knox, yet none of them will root the latest build of the Verizon Galaxy S6 Edge. On the plus side, the latest build does have radio improvements.
Will there be any rooted ROMs after OE2?

Unless the bootloader gets unlocked chances are nil

Install EMUI 5 on EVA L09C521B140

As the title says, how can I install the android 7 OTA on my P9 EVA L09C521B140? In the post http://forum.xda-developers.com/p9/development/rom-stock-rom-eva-l19c636b168-t3419586
I saw that the OTA for NXT-L09C521B140, it serves me the same? In what changes?
Thank you very much
I'm interested in this as well. I'm assuming you're interested in unbranding your phone as I am? Got it from a carrier, right?
If you find out anything regarding this please do let me know.

That post is old and it hasnt been updated it ages, if you want to know the latest firmware for your C521, best to download an app called Firmware Finder and check in there, B361 is the official released Android 7 firmware.

Hi, thanks for replying.
This is only the second day I have this new phone. I got it from my carrier so it has their brand at boot, the crappy bloatware they tend to put etc.
What I would like to do (at least until the devs manage to release a stable CM version for the phone) I'd like to get the OFFICIAL stock rom (unbranded, like bought from a store)
Could you point me somewhere where I could find how to do it, where to start etc? I'm all for learning myself but a start-point would be nice.
If I'm not mistaken, the model is EVA-L09 so C521 would be the variant? and B140 the firmware version, correct? And what's with the "cust" version at the bottom? carriers firmware?
Also, I've been reading and apparently NOUGAT is still in beta for these phones? So I guess I'd like to update to latest MM, and then update whenever they decide to release OTA.
Thanks in advance.
EDIT* TL;DR, Basically, I want to unbrand the phone. Remove my carriers bloatware. Just like a store bought phone.

If you look through the guide section of this forum, you will find what you been looking for. If you are looking at debranding and getting on to Nougat, you can follow this guide. Also, Nougat (EMUI 5.0) is now being officially rolling out but at a very slow pace.

N910T3 actually came with 5.1.1 lollipop out of the box there is no kitkat available or even 5.0 lollipop.
And even more bad news is N910T3 once upgrade to marshmallow there is no way to downgrade to lollipop because of locked bootloader.
N910T variant is only possible to downgrade from marshmallow to lillipop and kitkat.
And why do you wanna do that anyway ?
Kitkat is outdated almost 3 years old now and many apps and games required 5.0 or higher to run.
Stick with marshmallow its not that bad .
or if you really wanna go back to kitkat you can swap your t3 to T variant thats all i can say.
